Came across this by chance, and wondered if I knew you. I frequented the 'Gate from 1980 until it shut, and was in the Pool Team too. I am Ray, and in those years I had a ponytail. Yes, I know, many others did too!
After closure, the gigs and bikers transfered to the Peartree Bridge Centre, which also shut in about '86, soon demolished and replaced by grotty housing.
